Description:

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to slippers and more particularly, to
a paddle slipper that offers wearing comfort.

[0003] 2. Description of the Related Art

[0004] When playing a water game, taking a hot spring bath or SPA
treatment, or participating in outdoor activities during a leisure time,
people may wear a pair of slippers for the advantages of wearing comfort.
However, the user's sole will feel uncomfortable when the slipper is
water-wetted.

[0005] In order to eliminate the aforesaid water-wetted problem, breathing
slippers that can discharge water or be dried quickly are created.
However, the user's sole will still feel uncomfortable during the waiting
time before the water-wetted slipper is dried, i.e., the aforesaid prior
art design of breathing slippers is still not satisfactory in function,
and an improvement in this regard is necessary.

SUMMARY OF THE INVENTION

[0006] The present invention has been accomplished under the circumstances
in view. It is the main object of the present invention to provide a
paddle slipper, which lowers the chance of water-wetting the sole of the
user's foot when the user is paddling and, which offers wearing comfort.

[0007] To achieve this and other objects of the present invention, a
paddle slipper comprises an insole for the contact of the sole of a
user's foot, and an outsole bonded to a bottom side of the insole for
contacting the ground. The outsole comprises, at a bottom side thereof, a
front open zone extending backwardly from a front edge thereof, a front
support zone located on a front half of the bottom side thereof and
disposed at a rear side relative to the front open zone and having at
least two front protruding blocks and a front groove defined between two
front protruding blocks, and a rear support zone disposed at a rear side
relative to the front support zone and having at least one rear
protruding block. Thus, the front and rear support zones of the outsole
lift the insole to keep the user's sole above the ground at a distance,
lowering the chance of water-wetting the sole of the user's foot when the
user is paddling. The groove defined between the front protruding blocks
of the front support zone enables the corresponding part of the paddle
slip to be elastically curved during walking. The front open zone enables
the paddle slipper to incline forward for smooth walking. Thus, the
insole is elastically curved to fit the user's sole perfectly,
facilitating pressure release. Therefore, the paddle slipper offers
wearing comfort when the user walks.

[0008] It is still another object of the present invention to provide a
paddle slipper, which guides water rapidly away when the paddle slipper
is water-wetted, assuring wearing comfort.

[0009] To achieve this and other objects of the present invention, the
insole of the paddle slipper comprises a plurality of horizontal drainage
channels and a plurality of vertical drain holes respectively disposed at
the top side in communication with the horizontal drainage channels. When
the paddle slipper is water-wetted, water flows through the vertical
drain holes into the horizontal drainage channels and then guided to the
outside by the horizontal drainage channels. Therefore, the paddle
slipper discharges water rapidly, eliminating the problem of
uncomfortable feeling due to wearing of a water-wetted slipper.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Referring to FIGS. 1 and 2, a paddle slipper 10 in accordance with
a first embodiment of the present invention is shown comprising a vamp
20, an insole 30 and an outsole 40.

[0022] The insole 30 is formed of three sheet members, namely, the first
sheet member 31, the second sheet member 32 and the third sheet member 33
that are bonded together in a stack. The first sheet member 31 has
multiple vertical drain holes 312 that are tapered holes reducing in
diameter from the top side toward the bottom side. The second sheet
member 32 is bonded to the bottom side of the first sheet member 31,
having a plurality of horizontal drainage channels 322 transversely
extending through left and right sides thereof Each vertical drain hole
312 is kept in communication with one respective drainage channel 322 so
that water can be guided away from the top wall of the first sheet member
31 through the vertical drain holes 312 into the horizontal drainage
channels 322 and then discharged out of the insole 30. The third sheet
member 33 is bonded to the bottom side of the second sheet member 32,
having 5 locating holes 332. The vamp 20 comprises 5 mounting portions 22
that are respectively positioned in the locating holes 332 to secure the
vamp 20 to the insole 30. The vamp 20 defines with the insole 30 a
wearing space for accommodating the user's foot, avoiding separation of
the user's foot from the paddle slipper 10 when the user is walking.
Further, while achieving the aforesaid function, the vamp 20 can be made
in any shape. The shape shown in FIGS. 1 and 2 is not a limitation.

[0023] The outsole 40 comprises an outsole body 41 bonded to the bottom
side of the insole 30, and 4 anti-slip strips 42 fastened to the bottom
side of the outsole body 41. The bottom side of the outsole 40 is
configured to provide, in proper order from the front side toward the
rear side, a front open zone 43, a front support zone 44, a rear support
zone 45 and a rear open zone 46. The front open zone 43 is an opening
that extends backwardly from the front edge of the outsole 40. The front
support zone 44 comprises a first front protruding block 441 located on
the rear side of the front open zone 43, a second front protruding block
442 located on the rear side thereof, and a front groove 443 defined
between the first front protruding block 441 and the second front
protruding block 442. The rear support zone 45 comprises a first rear
protruding block 451 located on the front side thereof, a second rear
protruding block 452 located on the rear side thereof, and a rear groove
453 defined between the first front protruding block 451 and the second
front protruding block 452. The first and second front protruding blocks
441,442 and the first and second rear protruding block 451,452 extend
transversely between the left and right sides. The rear open zone 46 is
an opening that extends forwardly from the rear edge of the outsole 40 to
the second rear protruding block 452. The outsole body 41 can be made
directly by means of injection molding technology. Alternatively, the
outsole body 41 can be made by cutting and/or grinding a blank to form
the desired front open zone 43, front groove 443, rear groove 453 and
rear open zone 46, or by bonding different thickness block members 412
into the desired shape (see FIG. 3).

[0024] In the outsole 40 of the aforesaid paddle slipper 10, the first
front protruding block 441, the second front protruding block 442, the
first rear protruding block 451 and the second rear protruding block 452
each have an anti-slip strip 42 located on its bottom side. The bottom
wall of each anti-slip strip 42 for direct contact with the ground is
corrugated, having anti-slip properties. Further, the front support zone
44 and the rear support zone 45 are respectively located on the front
half part and rear half part of the outsole 40 so that the first and
second front protruding blocks 441,442 and the first and second rear
protruding block 451,452 can support the paddle slipper 10 on the ground
in a balanced manner, keeping the top wall 34 of the insole 3 above the
ground at a distance for the contact of the sole of the user's foot,
lowering the chance of water-wetting the sole of the user's foot when the
user is paddling.

[0025] Referring to FIG. 4, the point at the bottom side of the outsole 40
that is spaced from the front edge of the outsole 40 at a distance equal
to 1/3 of the length L of the paddle slipper 10 is within the front
groove 443, and the point at the bottom side of the outsole 40 that is
spaced from the rear edge of the outsole 40 at a distance equal to 1/6 of
the length L of the paddle slipper 10 is within the rear support zone 45,
thus, when the user wears the paddle slipper 10 of which the length L is
slightly greater than the length of the sole of the user's foot and
stands up, the center of gravity of the front half of the sole of the
user's foot and the center of gravity of the rear half of the sole of the
user's foot are respectively vertically located insole 30 corresponding
to the front groove 443 and the rear groove 453. The front groove 443 and
the rear groove 453 enable the corresponding parts of the paddle slipper
10 to be curved when the user imparts a pressure to the paddle slipper 10
through the sole, causing the insole 30 to fit the curvature of the sole
of the user's foot for immediate release of pressure. Further, the length
L1 of the front open zone 43 is within the range of 12˜18% of the
length L of the paddle slipper 10, or preferably at about 15%. The length
L2 of the rear open zone 46 is within the range of 6˜9% of the
length L of the paddle slipper 10, or preferably at about 7.5%. The front
open zone 43 or rear open zone 46 enables the paddle slipper 10 to
incline forward or backward subject to curving of the sole of the user's
foot when the user is walking, and therefore user wearing the paddle
slipper 10 can walk smoothly. Further, as shown in FIG. 5, the outsole 40
can be made having a front bevel 432 and a rear bevel 462.

[0026] Thus, when a user wearing the paddle slipper 10 is paddling, the
sole of the user's foot and the top wall 34 of the insole 30 will not be
wetted by water easily. Even if the paddle slipper 10 is wetted by water,
water can be rapidly carried away, eliminating the discomfort feeling of
wearing a wetted slipper. Further, the paddle slipper 10 offers wearing
comfort when the user is walking or paddling.

[0027] Further, as shown in FIG. 6, the front support zone 44 can be
designed to provide only one single front protruding block 444 to lift
the insole 30 in a balanced manner. Similarly, the rear support zone 45
can be designed to provide only one single rear protruding block 454 (as
shown in FIG. 7). Further, as shown in FIG. 8, the first and second front
protruding blocks 441,442 and the first and second rear protruding block
451,452 can be corrugated, achieving the same effect as the embodiment
shown in FIGS. 1 and 2. Further, as shown in FIG. 9, the front support
zone 44 can be configured to provide multiple front protruding blocks 446
that are arranged around a circle; the rear support zone 45 can be
configured to provide multiple rear protruding blocks 456 that are
arranged around a circle. The front support zone 44 and the rear support
zone 45 achieve the same effect of lifting the sole of the user's foot
and releasing the pressure from the sole of the user's foot.

[0028] Further, the insole 30 can be made by bonding one single upper
sheet member 35 and one single bottom sheet member 36 in a stack (see
FIG. 10 and FIG. 11), wherein the upper sheet member 35 has multiple
horizontal drainage channels 354 transversely extending through the left
and right sides thereof, and multiple vertical drain holes 352
respectively disposed in communication with the horizontal drainage
channels 354; the bottom sheet member 36 has 5 mounting holes (not shown)
for the mounting of the mounting portions 22 of the vamp 20.

[0029] Although particular embodiments of the invention have been
described in detail for purposes of illustration, various modifications
and enhancements may be made without departing from the spirit and scope
of the invention. Accordingly, the invention is not to be limited except
as by the appended claims.
